BMW 188K Ring & Pinion 4.10 Motorsport
BMW Motorsport Crown and Pinion to suit late model 6 cylinder BMWs including E38, E39, E46 and E60 These are new gears. These fit vehicles with the 4 or 6 bolt flange input shaft. These do not fit the later vehicles which take a 188L/LW gear set with a long spline input (no input flange). These gears are new.
Why not add an LSD while you're changing the gear ratio? It's a good time to install and LSD while you're there. If installing locally, you will also need a differential rebuild kit. If your LSD is worn beyond acceptable limits, you can also install an LSD rebuild kit.
We can rebuild your diff for you. We offer reasonable return postage rates via Couriers Please. Contact us for a fast quote.
*Bearings may still be installed. These must be discarded. Gears are generally used unless specified otherwise. They are removed from working differentials. These must be installed either by me or by a professional and competent diff builder. See our Recommended Diff Builders page for more info.
